Ok
MultiAction is x-row, right? RowMutation has the row prefix.
But if you think it makes it clearer, go for it.

bq. Review request for hbase.

bq. Summary
bq. -------
bq.
bq. Add API for atomic row mutations to HBase (currently Put and Delete).
bq.
bq. Client API would look like this:
bq. Delete d = new Delete(ROW);
bq. Put p = new Put(ROW);
bq. ...
bq. AtomicRowMutation arm = new AtomicRowMutation(ROW);
bq. arm.add(p);
bq. arm.add(d);
bq. myHtable.mutateAtomically(arm);
bq.
bq.
bq. This addresses bug HBASE-3584.
